PANNEL DISCUSSION Common Frequencies vs. Frequency Diversity in Civil Signals-What is the Right choice? - (PPT)

摘要

Common Frequencies or Frequency Diversity 1. Common frequencies are generally desirable (1). They simplify receiver design (not that significant with modern circuit design capabilities) (2). Can also simplify antenna design (nearby frequencies are not a problem) 2. Frequency diversity could be beneficial in some situations (3). In the presence of jamming the diversity of frequencies in the different systems might allow continued operation 3. The maximum spacing of the frequency separation is more important than commonality.
